twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches. How many square inches of dough are left over

valentina_108 [34]

Given:

Here twelve cookies are cut from a rectangle of dough measuring 12 inches by 16 inches.

Required:

How many square inches of dough are left over

the radius of cooke is 2 inches because if we cut cookie s in this formation and we get 4 cookies in horizontal so there are 4 diameter of each cookie and the total of these 4 diameter is 16.

So now the measure of one cookie is

$\frac{16}{4}=4\text{ inches}$

now the diameter of one cookie is 4 inches so by this we can find the radius

$\begin{gathered} r=\frac{d}{2} \\ r=\frac{4}{2}=2\text{ inches} \\ \end{gathered}$

now first we find the area of dough which isin rectangle shape

area of rectangle is

$A_1=12*16=192\text{ inches}^2$

now we have to find the area of 12 cookies

area of cookies is

$A_2=12*\pi *r^2=12*\pi *4=48\pi\text{ inches}^2$

now after cut dough for 12 cookies and the left over dough is

Final answer:

$A=A_1-A_2=192-48\pi\text{ inches}^2$

Solve the equation. If there is no solution, select no solution. -2|h-7|=-28

dedylja [7]

Answer:

C). h = –7, h = 21.

Step-by-step explanation:

-2|h-7| = -28

Divide both sides by -2:

|h - 7| = 14

The vertical lines means the absolute value of h - 7. The h - 7 may be positive or negative so we have 2 equations:

h - 7 = 14

So h = 21.

and h - 7 = -14

so h = -7.

If an=5n-3 find the common difference

Hitman42 [59]

Answer:

d = 5

Step-by-step explanation:

The common difference d of an arithmetic sequence is

d = a₂ - a₁ = a₃ - a₂ = $a_{n}$ - $a_{n-1}$

Given

$a_{n}$ = 5n - 3

Generate the first 2 terms of the sequence by substituting n = 1, n = 2

a₁ = 5(1) - 3 = 5 - 3 = 2

a₂ = 5(2) - 3 = 10 - 3 = 7

d = 7 - 2 = 5
